> Maybe filling big pools with water just so you can swim around will be seen as disgusting waste.

I have seen that being discussed recently, but I wonder: is it really a significant waste?

How much water does it consume, compared to say having a garden, or a green lawn?

Most pools have filtration systems and rarely require to be fully emptied then refilled.

It seems a class-based attack on people who can own pools, and therefore a dogwhistle, because the same attack could be made on taking a shower every day.
